2C! So pretty and very long too. What's the shortest you've had it? Did it curl up more or less when it was short? Right now I don't see any ringlets (whirly curls) but I think they can be achieved with the right regimen. Don't be afraid of gel. The rights ones will not cause crunch. So far I've gotten crunch with three gels but not three others. Also you could try a mousse.

P.S. Be careful with the ACV rinses. Once a month or so they're really great for your hair, but more than that they can dry it out. But then everybody's hair type is different and I know some people do it every week and are okay. I just have porous hair too and it's quite dry so I'm wary.
